that is exactly the problem here:
You BELIEVE, you DON'T KNOW!
And if you start blaming and/or defaming somebody, you should better know exactly, what you are talking about.

But it seems that you not even read my posting carefully and/or completely.

To stand by the facts:
I am NOT the owner, founder, creator, whatever ... of the PM Primer. This is David Litten and you would know that if you had a closer look on this.
And if you would have carefully read my posting, you would have recognized that i even don't promote the PM Primer.
In contrast to this, i had critized it and recommend against it.
Btw. I posted the link exactly ONCE.

Well, becoming abusing without any reason is often a sign of weakness and immaturely and for sure it should not be a behavior of an upcoming pmp.

If you are not able to discuss in an objective mannor, than you will never be able to become a good project manager.
May be, you will earn your certification one day.
But for sure, you will never become a
Project Management PROfessionell. GOt it?

However, may be we had a bad start and i am not resentfully, so i wish you all the best and a great career in PM.
